Ghost Wolf Bug

Recently, within the past few weeks, I have been having an issue on all of my shaman characters that I had not experienced previous. Whenever I try to cast a spell immediately out of ghost wolf (thus breaking wolf form), the spellcast becomes interrupted as if I had caused the interruption through character movement. This is not the case. Even when I stand completely still and try to cast a heal or lightning bolt on an enemy from ghost wolf form, the spell immediately becomes interrupted and I'm forced to cast the spell a second time. This also applies to casting a mount. If anyone else is having this problem, please let me know if you have found any remedy to this. Other than that, I certainly hope this will be fixed by the next patch, although I have not heard or seen anything regarding hotfixes or patch changes on this matter. In a very minor way, it takes away from the fluidity of the game while playing the shaman class. Also, if anyone has also experienced this (or not), it would be nice to know as well (I need to know I'm not crazy!). xD
